摘　　要：正弦脉宽调制(SPWM)在逆变器调制方法中应用最为广泛。通过双重傅里叶变换建立了双极性SPWM调制方法的数学模型,引入了一种新的仿真模块。通过数学模型对双极性SPWM调制方法的输出电压的谐波特性进行了定量分析,利用PSpice/ABM模块成功实现了逆变电路的双极性SPWM调制仿真,在实验室研制的1.5 k W单相全桥逆变器上进行了双极性SPWM调制方法的实验。通过仿真和实验结果的对比,验证了双极性SPWM调制方法的输出电压的谐波理论分析的正确性。Sinusoidal pulse width modulation（SPWM） was most widely used in the modulation of inverter. In order to analyze the harmonic in detail, the Double Fourier transform was used to establish the mathematic model of Bipolar SPWM, and a new simulation model was recommended. The Bipolar SPWM simulation of inverter circuit was realized by Pspice/ABM module. The validity of the theoretical analysis was verified by the results of simulation and experiment based on 1.5 k W Single-phase full-bridge inverter.
